The Lowdown
Alright, let’s talk about Jaconé. The forecast kicks off Thursday the 16th of July with a small, rideable swell. The water temp is 72°, right on average for the time of year, so no surprises.
Thursday afternoon sees a 4ft swell from the southeast, period around 10 seconds, with a cross-offshore wind from the east at 9 mph. The combined energy is moderate (334). It’s clean, but the wave comment says it’s marginal, so don’t expect too much.
Friday the 17th is better. Morning offers a clean 3ft southeasterly swell with a 10-second period, and a light offshore breeze from the north-northeast at 6 mph. That’s a good combo for some fun waves. The combined energy is moderate (343). The afternoon drops a bit to 3ft, still clean.
Saturday the 18th morning brings more size – 5ft from the east-northeast, but the period is short at 7 seconds, so it’ll be a bit messy. The energy is moderate (434). The wind is cross-offshore, still clean. The afternoon fades to 2ft; not worth it.
Now, Sunday the 19th morning is the first real highlight. A solid 6ft from the east-northeast, 8-second period, with a clean offshore breeze from the northeast at 9 mph. The combined energy is strong (548). This is the best of the first week – clean, consistent, with some punch. The afternoon drops off.
Monday the 20th morning is another good one: 5ft from the east-northeast, 8 seconds, light offshore breeze. Energy is moderate (393). Clean.
The middle of the week is quiet. Tuesday the 21st and Wednesday the 22nd are small and flat, with energy dropping below 100 at times. Thursday the 23rd sees a shift to a 3ft swell from the south-southwest, 9 seconds, with glassy conditions in the morning. A rare calm moment, but tiny.
Friday the 24th morning is glassy again with a 3ft south swell at 9 seconds – energy is moderate (250), clean. The afternoon turns poor with onshore wind.
Here’s the real standout. Saturday the 25th morning delivers a 6ft south swell, 10-second period, with a light offshore breeze from the north-northeast. The combined energy jumps to 608 – strong. This is the pick of the whole forecast. The afternoon gets even bigger – 7ft from the south, 12-second period, but the wind turns cross-offshore and the energy is massive (1547). That’s a serious swell, but it’s pushing into expert territory, especially for a beach break. The long period means better waves but longer lulls.
Sunday the 26th is big but messy. 8ft south swell at 13 seconds in the morning, but with cross-onshore wind. The energy is huge (1759), but the wind chops it up. Not great for paddle surfing; this setup looks more interesting for kite surfing.
The following week fades. Monday the 27th morning is glassy with a 4ft south swell, 11 seconds – clean, but small. The rest of the days are tiny, with occasional clean windows but nothing exciting. The 30th of July has a 4ft south swell with a very long 14-second period, but a cross-onshore wind spoils it.
Overall, the best on offer is Sunday the 19th morning for a solid, clean, fun session, and Saturday the 25th morning for the biggest, cleanest swell of the period – but that one’s for experienced surfers only.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
